Directory listing not showing

I've added the following to my httpd.conf file:

# Music directory addition
Alias /music "F:/Music"
<Directory "F:/Music">
Options +Indexes
</Directory>

I get the following error when trying to access the dir listing:

[Tue May 29 12:44:04 2007] [error] [client 68.*.151.*] client denied by server configuration: F:/Music/

Apparently there is something else I need to change in the httpd.conf file, but I don't know what :)
